Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7884, here are decompositions:

5 + 7879 = 7884
7 + 7877 = 7884
11 + 7873 = 7884
17 + 7867 = 7884
31 + 7853 = 7884
43 + 7841 = 7884
61 + 7823 = 7884
67 + 7817 = 7884

Showing the first eight; more decompositions exist.
